JAMES WILLIAM VHITMOEE, OF RICHMOND, VIRGINIA, ASSIGNOR OF ONE- FOUR-TH TO JAMES XV. VI'IITMOEE, JR., OF SAME PLACE.

HINGE.

SPECIFICATION forming'part of Letters Application filed August 18, 1885.

To all whom t may concern:

Be it known that I, J AMES W. Wnrrnonn, of Richmond, in the county of Henrico and State of Virginia, have invented new and useful Improvements in Hinges, of which thefollowing is a full, clear, and exact description.

This invention relates to hinges suitable for doors and gates of different kinds; and it consists in a hinge of novel construction, whereby it and the door or gute attached to it may be made self-closing or not1 as desired, substantially as hereinafter shown and described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a horizontal partly sectional View of a hinge embodying my invention, with the parts in position for producing a self-closing action of the hinge and showing the hinge as closed. Fig. 2 is a further longitudinal partly sectional View of the hinge under alike adjustment of its parts, but showing it opened; and Figs. 3 and 4,are similar Views to Figs. 1 and 2 ol'the hinge, but showing its parts as adj usted to make it not self-closing` A indicates the one half-section or leaf of which is designed to be secured on the door or gate, and A the other halfsection or leaf of the hinge to be attached to the frame which carries the door or gate.

B is the socket portion of the leaf A, arranged to extend above the upper edge of said the hinge,

leaf, and having a screw-thread, b, 0n the ein terior of its upper end, and square or angular chamber or aperture, c, in and through its upper end in direction of the length of the socket. rlhe screw'threaded end b of the socket B serves to receive over and to engage with it a screw-eap,- C, by which the adjustment is made to convert the hinge into a selfclosing or nonclosing one, as desired. Fitted to slide up and down within the angular chamber o is a correspondingly-shaped coupling, D, having a shank, d,which passes up through or within the screw-cap C, and admits of the screw-cap turning about or around it, but by means of a pin or screw, e, ventering within an annular groove, f, in the shank, insuring the coupling D rising and falling with the screwcap.

Patent No. 333,375, dated December 29.1885.

Serial No. 174,747. (Modelo B' is the socket portiouof the other leal", A', of the hinge constructed to enter np and turn within the lower end of the other socket l," and provided with an up wn rdlj-'proj eci ing fast hinge-pin, E, that engages with an elongated nul'` (l, which is i'ree to turn and rise and fall wilhin n clnunber, h, in tbc upper end oi' the socket l'. rlhe upper end of this nut G is constructed to engage by an angular shank, socket, j, in the lower end of the coupling D, so as when engaged to turn with said coupling, but permitting oi' its disengagement from the coupling.

Accordingly as the screw-cap G is turned to the right or to the left, when the hinge is secured by its leaves A A. to tbe door or gate and its frame, will the hinge and the door or gate be made self-closing or not, as desired. These adjustments of the screw-cap made when the hinge is closed. Thus, supposing the hinge to be closed, as shown in Fig. 1, and the screw-cap C to be screwed down, as there shown, then thecoupling D will be caused to engage with the nut G, and on opening the door or gate the leaf A of the hinge and door or gate att-ached thereto will be raised onefourth of an inch, more or less, by the unscrewing of the nut G on the screw g of the pin E, as shown in Fig. 2. Thus, be applied to the door of an apartment, it will enable the door to clear the carpet, and on re leasing hold of the door it and its attached leaf part A of the hinge will be made self-closing by their own Weight, down of the nut G on the thread g of the pin E, again bringing the upper and lower edges of the leaves A A into line with one another, as shown in Fig. 1. By unscrewirg or raising the cap C, as shown in and door or gate are closed, then the couplingpin D will be disengaged from the nut G, and the hinge, when opened, as shown in Fig. 4, or closed, as shown in Fig. 3, will operate as an ordinary hinge, and its leaf A, with its at- 95 venient, and any unskilled hand, or even a 10o on which is a sclmr-ihrearl, g, 55
